The device is an adjunctive tool for visualizing ultrasound images and assisting needle-targeted procedures; it does not directly treat or cure any condition.
No
The device is described as an "adjunctive tool" for visualization and assistance in needle-targeted procedures, such as biopsies. It does not provide a diagnosis itself, but rather aids physicians in performing diagnostic and interventional procedures by providing guidance and information visualization.
No
The device description explicitly states that the NaviGo™ Workstation "connects to the video output of the ultrasound system and by tracking the ultrasound probe's position". This indicates a physical connection and interaction with hardware (the ultrasound system and probe), which goes beyond being solely a software application.
Based on the provided information, the UC-CARE NaviGo Workstation is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- NaviGo Workstation's Function: The NaviGo Workstation is an adjunctive tool for ultrasound guided procedures. It processes and visualizes medical images (ultrasound and DICOM/MRI) to assist physicians in planning and performing procedures like prostate biopsies. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "2-D and 3-D visualization of ultrasound images of the prostate gland" and to "assist needle targeted procedures (e.g. biopsy)". This is focused on image guidance and procedural assistance, not the analysis of biological samples.
The device is a medical imaging and guidance system, falling under a different regulatory category than IVDs.

Device Description
The NaviGo™ Workstation is an adjunctive tool in the management of prostate diagnostic and interventional procedures. The NaviGo™ Workstation allows prostate needle tracking, recording, and management solution. The NaviGo™ Workstation is designed to assist the physician in performing prostate diagnostic and interventional procedures by providing regional orientation information, displaying a 3D model with real-time tracking and recording of the needle location. The NaviGo™ Workstation offers the ability to fuse DICOM originated information (e.g. MRI) with the ultrasound images and thus superimpose information from one modality onto the . The device includes means to compensate for patient body and prostate motion at any time during the procedure.
The NaviGo™ Workstation is designed to work with standard trans-rectal ultrasound systems and biopsy setup without changing or interfering with the physician's existing workflow. The NaviGo™ Workstation connects to the video output of the ultrasound system and by tracking the ultrasound probe's position, the recorded 2D ultrasound images are transferred to the NaviGo™ Workstation for viewing and creation of a 3D model. As with any other procedure, the TRUS probe is used together with standard disposable cover sheath supplied by the user.
Two dimensional (2D) images and the 3D model of the prostate are displayed on the NaviGo™ Workstation's screen. The NaviGo™ Workstation is equipped with tools to manipulate (rotate, pan, zoom) the model, and to archive and retrieve the information for further use.
The tracking and recording enables display of an accurate 3D model of the prostate and to record needle locations on the model. Pathology diagnosis results may be updated on the 3D model and a color display representation provides a visual display of the biopsy results.
The NaviGo™ Workstation supports the display of ROIs on the 3D model and displays visual indication when the needle trajectory intersects with an ROI (region of interest) is defined by the physician by segmenting a portion of the prostate on a 2D image and displaying its location on the 3D model, thereby defining a portion of the prostate as a target to direct a needle within. The 2D model for segmentation of the ROI can be either an Ultrasound image frozen during the procedure or a DICOM complaint image from another imaging study completed prior to the Ultrasound procedure (e.g. MR) when selecting the fusion procedure to display the planned targets. The ROIs are clearly numbered and labeled by a letter symbolizing it origin (Ultrasound or DICOM), On each image, more than one ROI may be defined (segmented).
The live 2D ultrasound image is superimposed in real-time with the 2D ROI boundaries thus allowing the physician to see the real-time advancement of the needle on the live ultrasound image with reference to ROI boundaries. The 3D model is displayed on a separate window alongside the ultrasound's live continuous images display, allowing prostate 3D orientation.
Regardless of the type of ultrasound probe used for the procedure (side-fire or end-fire) a cannula for a needle is built within the outer shell of the probe and therefore a needle can be inserted through the designated cannula. The designated cannula defines the needle path along its trajectory. The needle trajectory is displayed on the 3D model representing the potential needle route to allow the physician to direct the needle in real time into the target. When the projected path intersects with an RQL the color of the ROI will change indicating the needle can be directed inside the ROI if the physician ensures that the needle is inserted deep enough.
During the procedure, the physician may change some of the parameters on the US system or perform different actions that require the NaviGo™ Workstation to adjust. A physician may wish to freeze an image and perform measurements, label the image and save it to the report, switch between transversal and longitudinal view, or change the view of the ultrasound image. The NaviGo™ Workstation is equipped with image state algorithms to automatically detect the change in parameters and adjust itself to the new parameters. For example, if the physician freezes the US image, the NaviGo will automatically present additional menu option for a frozen image like measurements tools and labeling. The image state algorithm was developed to support generic ultrasound parameters and is specifically tested for each new ultrasound the NaviGo™ is required to support.
In off-line mode, the NaviGo™ software further enables the physician to analyze previous procedures using the prostate model, update the 3D model if necessary, update the recorded biopsies' locations, generate report, and provides a DICOM (e.g. MRI) interface for ROI definition, 3D model display, and data communication.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Fusion accuracy performance test:
The accuracy of targeting DICOM (MRI) derived regions of interest (ROI) by using the NaviGo Workstation was evaluated. Four phantoms each with 3 isoechoic lesions (CIRS Model 778-05, containing 3 randomly located isoechoic lesions of 0.5 cc) were targeted 2-3 times each using the NaviGo MRI fusion algorithm. Two phantoms were targeted using side fire ultrasound probes and two phantoms were targeted using end fire ultrasound probes. Needle location were defined relative to the ROI center line and accuracy is defined as the difference in needle location between the needle trajectory (targeted location in lesion) as marked on the real time US image, to the actual result as seen in post procedure CT scan. A total of 34 ultrasound guided biopsies were targeted into 12 isoechoic lesions. All 34 biopsies (100%) successfully hit the target lesion with an average error of 1.32±0.84mm. 32.3% of the biopsies had accuracy of

Non-clinical Performance Data:
The performance characteristics and operation/usability of the modified NaviGo™ Workstation were evaluated in the following non-clinical (bench) testing.
Fusion accuracy performance test:
The accuracy of targeting DICOM (MRI) derived regions of interest (ROI) by using the NaviGo Workstation was evaluated. . Four phantoms each with 3 isoechoic lesions (CIRS Model 778-05, containing 3 randomly located isoechoic lesions of 0.5 cc) were targeted 2-3 times each using the NaviGo MRI fusion algorithm. Two phantoms were targeted using side fire ultrasound probes and two phantoms were targeted using end fire ultrasound probes. Needle location were defined relative to the ROI center line and accuracy is defined as the difference in needle location between the needle trajectory (targeted location in lesion) as marked on the real time US image, to the actual result as seen in post procedure CT scan. A total of 34 ultrasound guided biopsies were targeted into 12 isoechoic lesions. All 34 biopsies (100%) successfully hit the target lesion with an average error of 1.32±0.84mm. 32.3% of the biopsies had accuracy of
